Many puzzles and riddles on the Web that include audio files often hide clues or details in such a way that they do not appear on the 'surface' during playback, and require spectrographic analysis.
At the same time, there are archivists, signal processing researchers, and musicologists who need to visualize a song from a different angle. For them, the Queen Mary University of London develops and offers Sonic Visualiser, a robust free and open-source software that anyone interested in the technical aspect of audio should study.
Regardless of the audience it is aimed at, every audio editor has a certain learning curve. That raises a question: Is it better to have a multipurpose editor, or one with specific functions?
Sonic Visualiser falls into the second category. In fact, its name doesn't even suggest it's an editor. For example, you can open files in multiple formats, but when it comes to exporting content, it only supports .WAV.
The role of Sonic Visualiser is to help us observe and better understand different aspects of an audio file, which requires some prior preparation.
Visualizing audio file content
Although Sonic Visualiser includes several functions out of the box, this program lives and dies by its plugins. The tutorial called «Guía de Sonic Visualiser para Musicólogos» (only in English, I'm afraid) recommends from the beginning to download the Mazurka project plugin, and to that are added others created by the BBC, the University of Alicante, the Universitat Pompeu Fabra, and more.
In essence, Sonic Visualiser allows us to perform advanced analysis of a recording via computer, when before more complex and expensive resources were needed.
Tempo, averages, energy, intensity, peak detection, spectrograms... all this and much more is possible as long as a compatible plugin exists.
Want to add effects? Don't worry, the program supports LADSPA and DSSI. In the case of VST, the developers recommend exploring the 'Audacity Enabler' on Windows, or dssi-vst on Linux.
That brings us to its availability. As free and open source software, Sonic Visualiser is compatible with Windows, multiple flavors of Linux (only 64-bit), and MacOS 10.12 or higher.
Remember that plugins also go separated by architecture, and need to be placed in the correct folder within 'Program Files' and 'Program Files x86'.
Perhaps it is not the most intuitive program in the world at first, but if you are passionate about audio, you should download a copy of Sonic Visualiser and explore it thoroughly.
